Single-walled carbon nanotubes (SWCNTs) were suspended in aqueous media with cucurbit[7]uril (CB7), while SWCNTs were insoluble with cucurbit[5]uril (CB5). Moreover, defection-selective solubilization of SWCNTs with CB7 was demonstrated.

Surveys of yellowing viruses in plastic tunnels and in open field crops of melon (Cucumis melo cultivar catalupo), oriental melon (C. melo cultivar oriental melon), and cucumber (C. sativus) were carried out in two melon-growing areas in 2014, Korea. Severe yellowing symptoms on older leaves of melon and chlorotic spots on younger leaves of melon were observed in the plastic tunnels. The sympto...

2D pseudopolyrotaxanes containing beta-cyclodextrins and cucurbit[6]urils can induce DNA condensation, and the number of cucurbit[6]urils threaded onto the side chains of beta-cyclodextrins plays important roles in this process.

Cucurbit crops are mostly produced for their immature or mature fruits. However, a relatively high proportion of cucurbit fields are destined for seed production, either for seed consumption or for propagation material. Production of cucurbits for seed consumption (as a snack food) is very popular in some parts of the globe and almost unknown in others. Open-pollinated cultivars (inexpensive se...

Host-guest interactions between cucurbit[7]uril (CB7) and a cardiotonic drug, milrinone, have been explored using steady state and pico-second time-resolved techniques. A novel fluorescence switch from ultraviolet (UV) to visible (cyan) is observed as a consequence of upward pKa shift of the drug inside the nano-cavity of cucurbit[7]uril.

The genome components of the Melon chlorotic leaf curl virus (MCLCuV) were cloned from symptomatic cantaloupe leaves collected in Guatemala during 2002. The MCLCuV DNA-A and DNA-B components shared their closest nucleotide identities among begomoviruses, at approximately 90 and 81%, respectively, with a papaya isolate of MCLCuV from Costa Rica. The closest relatives at the species level were ot...

Nucleotide binding site leucine-rich repeats (NBS-LRR) accounting for the main disease resistance proteins play an important role in plant defense against pathogen attack. The current study aimed to identify new NBS-LRR gene members in native types of cucurbit species in Iran. Accordingly, DNAs of melon, cucumber and cantaloupe native types to Iran were identified using three primer pairs. PCR ...

Supramolecular capping of cucurbit[5]uril (CB[5]) by gold nanoparticles has been achieved via a facile reduction of an aqueous solution of HAuCl(4) by NaBH(4) in the presence of various amounts of CB[5]. The resultant assemblies were very stable in solution, and were found to form dynamic aggregates consisting of a controllable ratio of singly and doubly capped CB[5].

Biomass - that is a new feather in your cap: palm shell powder was used as support for novel uranyl complexed cucurbit[5]uril oligomer to obtain a selective extractant for uranium. The key to the selectivity lies in the perfect environment of the two portals of cucurbit[5]uril for uranyl ion binding.
